Jerry,,
Common sense should always rule the day. Even a 24 oz model at 35 mph can do some hurt if you are unlucky enough to get hit but the prop hub hub.

I just re-read my post and I made one error. "In an EP powered system the rpms are a reflection of the kV (rpms per volt) and as the propeller unloads the rpm does not increase, but the amp (current) draw does, effectively reducing the horsepower being delivered." This read "In an EP powered system the rpms are a reflection of the kV (rpms per volt) and as the propeller unloads the rpm does not increase, but the amp (current) draw <u>also decreases</u>, effectively reducing the horsepower being delivered."

Have fun!
